For example, a very useful service is the "Root Actions Servicemenu", which allows many functions to be performed with root (superuser or "sudo") permissions. This is necessary, for example, for editing text files that have root permissions.

The "Scan with ClamAV" service allows the anti-virus scanner to be run from Dolphin.

Once the new services have been installed, the system must be rebooted for the newly added service menus to appear in Dolphin.

<Right-click> on an item within Dolphin to bring up the services menu. For example, once the Root Actions Servicemenu has been installed, I can edit a text file with root permissions by <right-clicking> on it and selecting

Root Actions -> Open as text

This will open the text editor (kate) as root.

Other popular service menus include audiokonvertor, Extract and Compress, servicemenu-pdf, image2pdf, and vlcappend.

FFMpegThumbs uses FFMPEG to create thumbnail frames from video files, which can be used by KDE from a file manager like Dolphin. Install:

sudo apt-get install ffmpegthumbs

Alternatively, install kFFMpegThumbnailer (sudo apt-get install kffmpegthumbnailer), which works in a similar manner. (Both require FFMPEG to be installed.)

After installation of either of these modules, log out and log back into (or restart) your system for changes to take effect.

MPlayerThumbs not only shows a video frame thumbnail in Dolphin, it also has the capacity to show the entire video in the Dolphin Information side panel (for previewing). Though more powerful, it is slower to load than either FFMpegThumbs or kFFMpegThumbnailer. (MPlayer must also be installed for this thumbnailer / previewer to function.) Install:

sudo apt-get install mplayerthumbs

After installation, log out and log back into (or restart) your system for changes to take effect.

How to use network options in Dolphin file manager

Open the "Network" icon in Dolphin.

A network folder can also be mounted in the left navigation pane for repeated quick access. For example, a Samba (Windows-type) network folder located at a LAN IP address of 192.168.0.177 can be added:

Dolphin -> <right-click> on the leftmost panel -> Add entry...

-> Label: Network folder -> Location: smb://192.168.0.177

Accessing a digital camera from the Dolphin file manager

Plug in your digital camera to the USB port using the appropriate cord and make sure the camera is turned on.

Start the Dolphin file manager.

In the leftmost panel of the Dolphin file manager, mount the camera as a folder:
